Abstract

Based on Maxwell equations with source terms, EM responses for infinite line source of 2-D symmetrical anisotropic formation in frequency domain are computed. The partial differential equation solutions based on a finite element method of electric field parallel to line source for TE mode and magnetic field parallel to line source for TM mode are derived and calculated. The result shows that the TM mode can present the geoelectricl variations of earth model properly, while TE mode is less reliable compare with TM mode for situation of infinite line source. The value of TE mode is much larger than TM mode to at least two decades. By calculating the 2-D anisotropic anomalous body in either homogeneous half-space or one-dimensional layered media, the isotropic background and anisotropic anomalous body can be clearly figured out. By changing the anisotropic coefficient and rotation angle from main electrical axis of anisotropic model, it is obvious different from anisotropic case both for apparent resistivity and impedance phase curves.
